tnning the box fiom its normal hoi'izontal position to its extreme inclined position and again loack to the initial position, thereupon repeating this rocking Amotion as long,` as the ti'ansinission of the motion 'from the motor to the worm wheel continues, so that every loiealdown is avoi'ded.A The transmission of the motion can he interrupted at any moment without any danger of box moving ifuithei', which means, the tiitloox con he secured' in position, either in the noimai horizontal oi" in the e5;- t'ienie inclined position o'i' in any inteiinie diete' position. ieierably the conneeting rods elie made. in two iarts which 'are 'ptessed together ley means of springs and ablutinents ae provided on the cari-inge 'frame foi stopping the i'oolingg fname, so Ythat for the lowest position olf the cianltpins oic the crank-shaft the springs at thel seine time by means of the connecting rods press the front ei'id of the melting fname ifoin aliove against the ahutinents, so as to' prevent the rocking iframe iroin'viloiating duiing th e drive. Moreover the crank-shaft is preferably made in two paints, which aie connected with the worin wheel by means .clutches and the' pins for connecting the connecting rods with the-rocking 'ifaineaie piefei'ably provided with glohular siiifaes, so as to fiee the whole niechanisn'i from all objectionable influences oi' any distoition oi the carriage: frame.

In Fig. l the rear wheel at the front is omitted in order to better-show the invention, While the other rear Wheel G i9; merely indicated by a oirele.
